Is the administrator account an employee?
In addition to the employees present in the database, it is possible to log in as Administrator to manage all features without access-right limitations. This Administrator concept is not attached to an employee account: it is a super account, and it necessarily exists.
It is possible to create employee accounts with all rights, which you might call for example "Manager" to avoid confusion with the Administrator concept. Some technical configuration options are only accessible to the Administrator for security reasons.
